Description

The present invention relates to a brake system, and more particularly to a brake interlocking system that matches front wheel braking force and rear wheel braking force.

The braking system is a braking mechanism for decelerating or stopping the forward movement of the vehicle, and is used to stop the vehicle by decelerating the rotation of the wheels. In conventional vehicles, there are many methods to limit the movement of the two wheels, and if the brakes are erroneously operated during the braking process, the braking distance may be significantly increased, slippage due to tire brake lock, and in some cases, vehicle body unlocking. There is also the possibility of overturning due to balance, which reduces the safety of the vehicle.

In order to improve the safety of the vehicle and prevent improper operation of the front and rear wheel braking systems, the front and rear wheel braking devices are currently activated simultaneously by operating a single handle, and the front wheel braking force and rear wheel braking force and rear wheels A braking system has been proposed in which the front wheel braking force and the rear wheel braking force are matched, which is characterized in that the front wheels and the rear wheels act on the braking force at a predetermined ratio.

However, the greater the braking force of the entire vehicle, the more remarkable the vehicle inertia forward movement becomes, and if only a certain ratio of braking force acts on the front and rear wheels, the running vehicle cannot be stopped smoothly. In addition, when the front wheel braking force and the rear wheel braking force are linked, it cannot be avoided that the front wheels are locked up early due to an erroneous operation by the user, or the initial braking force is too large, so that the vehicle slips during the braking process. Or rollover may occur.

In order to solve the problems of the prior art, the front wheel braking force and the rear wheel braking force are effectively matched. Specifically, the front wheel braking force is operated after the rear wheel braking force is operated, and the vehicle inertia is applied. Attention is being paid to providing a brake interlocking system that can provide front wheel braking force and rear wheel braking force that change the non-linear ratio according to the effect.

An object of the present invention is to provide a brake interlocking system, which can generate sufficient braking force to satisfy a safety standard deceleration with a single handle operation. By operating a single handle, at least one adjustment rod member in the distribution force ratio adjustment mechanism is driven to ensure accurate distribution of front and rear wheel braking force, and the ratio of rear wheel braking force to front wheel braking force is non-linear. By changing the relationship, comfort, maximum deceleration and stability during vehicle braking can be obtained. In addition, the structure is rationalized, the cost is reduced, and the installation is easy. Further, in the operating mechanism of at least one rod member in the distribution force ratio adjusting mechanism, the range of change in the ratio of the front and rear wheel braking force can be widened, and the overall structure can be miniaturized.

Another object of the present invention is to provide a brake interlocking system in which the start delay assembly of the distribution force ratio adjusting mechanism is interlocked by a single handle operation, and the rear wheel brake mechanism can apply the brake first to brake. When braking in an emergency or on wet roads, the rear wheels lock before the front wheels.

Further, even if the front wheel brake mechanism fails, the rear wheel brake mechanism can generate a sufficient braking force.

Some exemplary embodiments that embody the features and advantages of the present invention will be described in detail below. It should be understood that the present invention is capable of various modifications in various aspects and the description and drawings herein are intended to be exemplary and not limiting.

FIG. 1 is a diagram for explaining the force action of the brake interlocking system according to the first embodiment of the present invention. FIG. 2 is a diagram showing the relationship between the first feed output and the second feed output of the brake interlocking system according to the first embodiment of the present invention. In the present embodiment, the brake interlocking system 1 includes a distribution lever 10, a feed-in assembly 20, a first delivery assembly 30, a distribution force ratio adjusting mechanism 40, and a second delivery assembly 50. The feed assembly 20 is, for example, a left brake handle assembly for the operator to operate the brake interlocking system 1. The first delivery assembly 30 and the second delivery assembly 50 can be, for example, a rear wheel brake mechanism and a front wheel brake mechanism, respectively. In one embodiment, the first delivery assembly 30 and the second delivery assembly 50 may be, for example, a rear wheel drum type brake mechanism and a front wheel disc type brake mechanism. The present invention is not limited to this. The delivery of the first delivery assembly 30 and the second delivery assembly 50 can be applied to drum, disc or other brake mechanisms, the details of which are not described herein.

In the present embodiment, the distribution lever 10 has a first end portion 11 and a second end portion 12, and the first end portion 11 and the second end portion 12 face each other. The feed assembly 20 is connected between the first end 11 and the second end 12 of the distribution lever 10 by inserting a pin to provide feed input F1 so that the distribution lever 10 is of feed input F1. It is configured to displace along the direction. The first delivery assembly 30 is connected to the first end portion 11 of the distribution lever 10 by inserting a pin to generate a first feed output F2 corresponding to the feed input F1 of the feed assembly 20. The distribution force ratio adjusting mechanism 40 can be slidably connected to the second end portion 12 of the distribution lever 10 by a pulley or other sliding member, and the modulation force corresponds to the feed input F1 of the feed assembly 20. Generate F3. As a result, the first end portion 11 and the second end portion 12 of the distribution lever 10 swing with each other. As the feed input F1 of the feed assembly 20 increases, the displacement generated by the distribution lever 10 also increases, the distribution force ratio adjusting mechanism 40 slides due to the displacement of the distribution lever 10, and the generated modulation force F3 has a constant value. Instead, it changes non-linearly according to the change of the input / input F1. On the other hand, the second delivery assembly 50 can also be slidably connected to the distribution force ratio adjusting mechanism 40 by a pulley or another sliding member, and the feed input F1 of the feed assembly 20 and the first delivery assembly 30 can be connected to the second delivery assembly 50. The second feed output F4 is generated corresponding to the first feed output F2 and the modulation force F3 of the distribution force ratio adjusting mechanism 40 (see FIG. 1). Since the second feed output F4 of the second delivery assembly 50 and the first feed output F2 of the first delivery assembly 30 are transmitted to the front wheel brake mechanism and the rear wheel brake mechanism with equivalent rigidity, respectively, the front wheel braking force and the rear wheel The ratio with the braking force becomes a non-linear relationship as the feed input F1 changes. The ratio of the second transmission output F4 of the second transmission assembly 50 to the first transmission output F2 of the first transmission assembly 30 becomes a non-linear relationship as the transmission input F1 changes (see the solid line portion in FIG. 2).

FIG. 3 is a perspective view of the brake interlocking system according to the first embodiment of the present invention. FIG. 4 is a diagram showing a start delay assembly of the brake interlocking system according to the first embodiment of the present invention. FIG. 5 is a perspective view showing a part of the configuration of the brake interlocking system according to the first embodiment of the present invention. In the present embodiment, the brake interlocking system 1 further includes a housing 60 having an accommodation space 61. The distribution lever 10 of the brake interlocking system 1 and the distribution force ratio adjusting mechanism 40 are housed in the accommodation space 61, and the distribution force ratio adjusting mechanism 40 is arranged in the housing 60. The feed assembly 20, the first feed assembly 30, and the second feed assembly 50 may be connected from the outside of the housing 60 according to actual usage requirements. The method of connecting the feed assembly 20, the first feed assembly 30, and the second feed assembly 50 is not particularly limited, and thus the description thereof will be omitted. In the present embodiment, the distribution lever 10 further includes a first pulley 13 arranged at the second end portion 12, and the distribution lever 10 is slidably connected to the distribution force ratio adjusting mechanism 40 via the first pulley 13. can do.

In the present embodiment, the distribution force ratio adjusting mechanism 40 includes a start delay assembly 40a and a force distribution force assembly 40b. The start delay assembly 40a is arranged in the housing 60 and is slidably connected to the second end 12 of the distribution lever 10 to generate a modulation force F3 corresponding to the feed input F1 of the feed assembly 30 to generate a second Delays the delivery assembly 50 from producing the second feed output F4. The force distribution assembly 40b is arranged in the housing 60 and is slidably connected to the second end 12 of the distribution lever 10 so that when the distribution lever 10 is displaced along the feed input F1, the force distribution assembly 40b And the distribution lever 10 are adjusted in contact position. In the present embodiment, the start delay assembly 40a includes a rotating member 41 and an elastic member 42, the rotating member 41 is pivotally contacted with the housing 60, and has a first arm 411 and a second arm 412. The first arm 411 has a curved surface 413, and the first pulley 13 of the distribution lever 10 is slidably connected to the first arm 411 of the rotating member 41 via the curved surface 413. In the present embodiment, the elastic member 42 is a telescopic spring, the second arm 412 of the rotating member 41 is connected to one end of the elastic member 42, and the other end of the elastic member 42 is connected to the housing 60. As a result, the rotating member 41 is driven to rotate, and the curved surface 413 of the first arm 411 is brought into contact with the first pulley 13 of the distribution lever 10, and the rotation occurs when the user operates the feed-in assembly 20. The elastic member 42 can provide the elastic force so that the member 41 is rotated by the feed input F1 and the modulation force F3 of the non-linear change is generated to resist the torque by the feed input F1. In one embodiment, the torsion spring may be used as the elastic member 42 to replace the telescopic spring, but the present invention is not limited thereto. In the present embodiment, the angle formed by the first arm 411 and the second arm 412 of the rotating member 41 is smaller than 180 degrees. Further, when the rotating member 41 rotates due to the displacement of the distribution lever 10 along the direction of the feed input F1, the first arm 411 of the rotating member 41 gradually becomes perpendicular to the distribution lever 10, and the rotating member 41 The contact action between the first arm 411 and the first pulley 13 of the distribution lever 10 is reduced, and the torque exerted by the elastic member 42 on the distribution lever 10 is also reduced. That is, the modulation force F3 generated by the rotating member 41 and the elastic member 42 of the start delay assembly 40a changes non-linearly, and the distribution lever 10 is displaced along the direction of the input F1, so that the modulation force F3 gradually increases. Reduce.

On the other hand, the force distribution assembly 40b includes at least one first rod member 43 and at least one second rod member 44. The first rod member 43 and the second rod member 44 are connected to the housing 60 via pins, respectively, and are spatially opposed to each other. In the present embodiment, the first rod member 43 includes a first end portion 431 facing each other, a second end portion 432, and a second pulley 433. The first end portion 431 of the first rod member 43 is connected to the housing 60 via a pin, and the second pulley 433 is provided at the second end portion 432 of the first rod member 43. When the distribution lever 10 is displaced along the direction of the feed input F1, the distribution lever 10 is displaced so as to come into contact with the second pulley 433 of the first rod member 43, and the first rod member 43 is the first rod member 43. It rotates around one end 431. Further, in the present embodiment, the second rod member 44 includes a first end portion 441 facing each other, a second end portion 442, and a third pulley 443. The first end portion 441 of the second rod member 44 is connected to the housing 60 via a pin, and the third pulley 443 is provided at the second end portion 442 of the second rod member 44. When the first rod member 43 rotates about the first end portion 431, the first rod member 43 comes into contact with the third pulley 443 in the second rod member 44, and the second rod member 44 touches the first end portion 441. The second rod member 44 is interlocked so as to rotate as a center and the contact portion 444 comes into contact with the second delivery assembly 50 to generate the second feed output F4. In the present embodiment, the second delivery assembly 50 is described by taking a disc brake mechanism as an example, and the second rod member 44 presses the oil pump in the disc brake mechanism by a contact method. The present invention is not limited to this. In another embodiment, the second rod member 44 may generate a second feed output F4 by a contact method, a pulling method, or the like and act on a drum type, a disc type, or another type of brake mechanism. The details will be omitted.

FIG. 6 is a diagram showing an interlocking relationship of each configuration of the brake interlocking system according to the first embodiment of the present invention. FIG. 7 is a diagram showing an initial state of the brake interlocking system according to the first embodiment of the present invention. FIG. 8 is a diagram showing an operating state of the brake interlocking system according to the first embodiment of the present invention. In the present embodiment, in the initial state of the brake interlocking system 1, the distribution lever 10 is held in the initial position due to the limitation of the start delay assembly 40a. As shown in FIGS. 3 to 7, the first end 11 and the second end 12 of the distribution lever 10 are connected to the first delivery assembly 30 and the start delay assembly 40a of the distribution force ratio adjusting mechanism 40, respectively. The feed assembly 20 is connected between the first end portion 11 and the second end portion 12. In one embodiment, the housing 60 is provided with a positioning convex member 63 with respect to the connection point of the feed-in assembly 20 in the distribution lever 10, and is in contact with the distribution lever 10 in the initial state of the brake interlocking system 1. The stability of the initial state can be improved. It should be noted that this structure is not a necessary technical feature of the present invention, and details will be omitted. By the way, since the distribution lever 10 is displaced along the feed / input F1 direction, the housing 60 further includes a guide groove 62. The distribution lever 10 is provided with a position limiting portion 14, which is provided adjacent to the connection point of the feed assembly 20 and is partially housed in the guide groove 62. As a result, the distribution lever 10 is displaced in the feed input F1 direction, and the distribution lever 10 is moved to the feed assembly 20 as the feed input F1, the first feed output F2, the modulation force F3, and the second feed output F4 change. The first end portion 11 and the second end portion 12 can swing around the connection point of the above.

In the initial state, the distribution lever 10 keeps a distance from the first rod member 43 of the force distribution assembly 40b, that is, the second pulley 433 of the first rod member 43 does not come into contact with the distribution lever 10. At this time, the force distribution assembly 40b is not stressed or pulls the second delivery assembly 50, so that the second feed output F4 is 0 (see the solid line portion in FIG. 2). That is, the numerical value of the second feed output F4 is 0 before the feed input F1 drives the distribution lever 10 to cause the distribution lever 10 to be sufficiently displaced by the second pulley 433 in the first rod member 43. That is, the brake interlocking system 1 controls the front wheel braking force to be generated later than the rear wheel braking force, so that the first delivery assembly 30 of the rear wheel braking mechanism applies the brake first, and the rear wheels are from the front wheels. It is locked first and can stop the rotation reliably. In another embodiment, when the first delivery assembly 30 of the rear wheel brake mechanism is unable to generate the first feed output F2 due to stress (such as disconnection or lockup), the distribution lever 10 limits the start delay assembly 40a. As a result, the first rod member 43 cannot be brought into contact with the first rod member 43, and the second delivery assembly 50 of the front wheel brake mechanism cannot be driven to generate the second feed output F4. That is, the brake interlocking system 1 of the present invention can function as a safety mechanism in addition to matching the front wheel braking force and the rear wheel braking force. If the first delivery assembly 30 of the rear wheel brake mechanism fails (for example, disconnection or lockup), the second delivery assembly 50 of the front wheel brake mechanism does not generate an interlocking braking force.

On the other hand, when the feed input F1 drives the distribution lever 10 to generate a displacement and the distribution lever 10 starts to come into contact with the second pulley 433 in the first rod member 43, the first rod member 43 has the first end portion 431. The first rod member 43 is brought into contact with the third pulley 443 in the second rod member 44. The second rod member 44 rotates about the first end portion 441 of the second rod member 44 due to the contact of the first rod member 43, so that the second rod member 44 comes into contact with the second delivery assembly 50. It is driven and produces a second feed output F4. When the distribution lever 10 drives the force distribution assembly 40b to abut the second delivery assembly 50, it is necessary to resist the modulation force F3 generated by the rotating member 41 and the elastic member 42 of the start delay assembly 40a at the same time. Further, since the modulation force F3 generated by the rotating member 41 and the elastic member 42 of the start delay assembly 40a is a non-linear change, the second feed output F4 of the second feed assembly 50 and the first feed output of the first feed assembly 30 The change in the ratio with F2 has a non-linear relationship as shown in the solid line portion of FIG. The second feed output F4 of the second delivery assembly 50 and the first feed output F2 of the first delivery assembly 30 are transmitted to the front wheel brake mechanism and the rear wheel brake mechanism with equivalent rigidity, respectively, and the front wheel braking force and the rear wheel are rear wheels. The ratio with the braking force has a non-linear relationship with the change of the input F1. When the distribution lever 10 is displaced along the direction of the feed input F1, the modulation force F3 generated by the rotating member 41 and the elastic member 42 of the start delay assembly 40a gradually decreases. As the transmission input F1 gradually increases, the modulation force F3 gradually decreases, and the gain of the second transmission output F4 gradually increases. In other words, the second feed output F4 of the front wheel braking force is slower than the generation of the first feed output F2 of the rear wheel braking force, and the second feed output F4 increases as the rear feed input F1 increases. It changes non-linearly and increases with the modulation force F3. The ratio of the second feed output F4 and the first feed output F2 becomes a non-linear relationship with the change of the feed input F1, and at the same time, the difference between the second feed output F4 and the first feed output F2 is reduced to brake the front and rear wheels. Efficiency can be effectively improved.

As a result, in the brake interlocking system 1 of the present invention, the rear wheels are locked before the front wheels and the rotation is stopped when performing emergency braking or braking on a wet road surface. If the rear wheel braking mechanism fails (for example, disconnection or lockup), the front wheels do not generate interlocking braking force. Further, even if the front wheel brake mechanism fails, the rear wheel brake mechanism can generate a sufficient braking force.

In the present embodiment, the second delivery assembly 50 is braked via the force distribution assembly 40b in the distribution force ratio adjusting mechanism 40. Since the force distribution assembly 40b includes at least two rod member operating mechanisms including at least one first rod member 43 and at least one second rod member 44, the feed input F1 drives the distribution lever 10. When the distribution lever 10 begins to abut on the force distribution assembly 40b, the actuating mechanism of at least two rod members is dimensioned along the displacement direction of the distribution lever 10, i.e., the feed input F1 direction. The second delivery assembly 50 can be pushed or pulled along the displacement direction of the distribution lever 10 in a small space. In another embodiment, the force distribution assembly 40b of the distribution force ratio adjusting mechanism 40 can increase or decrease the number of rod members according to demand, and the present invention is not limited thereto.

In the above-described embodiment, the brake interlocking system 1 is more excellent in robustness due to the design in which the front wheel braking force and the rear wheel braking force in the above-described operating mechanism are matched. Hereinafter, it is illustrated that the first delivery assembly 30 is a drum type rear wheel brake mechanism, and the fluctuation conditions of the drum type brake device are numerous and complicated. When the brake shoes in the rear wheel brake mechanism are worn or the brake wiring is not adjusted, the free spacing of the brake handles (or handlebar clearance) increases to provide the first delivery assembly 30 of the rear wheel brake device. The first feed output F2 is reduced. On the other hand, in the brake interlocking system 1 of the present invention, the above-mentioned operating mechanism matches the front wheel braking force and the rear wheel braking force, so that the handlebar clearance does not need to be recalled to the factory for adjustment. Also, it can be ensured that the first delivery assembly 30 of the rear wheel brake mechanism operates before the second delivery assembly 50 of the front wheel brake machine, and at the same time, the second feed output F4 and the second feed output F4 and the second feed output with an accurate non-linear relationship change and an accurate distribution ratio One feed output F2 can be provided. Please refer to the solid line part in FIG. The relationship between the first feed output F2 and the second feed output F4 is shown by the design curve of the brake interlocking system 1 of the present invention, and theoretically, the ideal curve of maximum deceleration (broken line portion) where both front and rear wheels are locked at the same time. ) Can be obtained. In the brake interlocking system 1 according to the present invention, the safety margin S is further increased by distributing the second feed output F4 and the first feed output F2. Therefore, in the brake interlocking system 1 of the present invention, the above-described operating mechanism is used. By designing the front wheel braking force and the rear wheel braking force in harmony, it is possible to have sufficient robustness and ensure that the braking force distribution of the front and rear wheels is not significantly deteriorated due to these factors.

FIG. 9 is a diagram showing an installation example of the brake interlocking system according to the first embodiment of the present invention.

(For example, it can be provided inside the vehicle body). Then, the first sending assembly 30, the second sending assembly 50, the feeding assembly 20, and the like are connected. The present invention is not limited to these. By controlling the feed assembly 20 using the left handle, the user can change the non-linear relationship of the brake interlocking system 1 and accurately obtain the second feed output F4 and the first feed output F2 (solid line in FIG. 2). The first delivery assembly 30 and the second delivery assembly 50 of the brake interlocking system 1 can be controlled as provided. As a result, the braking interlocking of the front and rear wheels can be completed, and comfort, maximum speed and stability during vehicle braking can be obtained.

FIG. 11 is a perspective view of the brake interlocking system according to the second embodiment of the present invention. FIG. 12 is a diagram showing a start delay assembly of the brake interlocking system according to the second embodiment of the present invention. FIG. 13 is a perspective view showing a part of the configuration of the brake interlocking system according to the second embodiment of the present invention. FIG. 14 is a diagram showing an interlocking relationship of each configuration of the brake interlocking system according to the second embodiment of the present invention. In the present embodiment, the brake interlocking system 1a is the same as the brake interlocking system 1 shown in FIGS. 1 to 10, and the same components are designated by the same reference numerals and description thereof will be omitted. The difference from the brake interlocking system 1 shown in FIGS. 1 to 10 is that in the present embodiment, the force distribution assembly 40b includes only the first rod member 43. The first delivery assembly 30 and the second delivery assembly 50 are, for example, a rear wheel drum type brake mechanism and a front wheel drum type brake mechanism.

The first rod member 43 is connected to the housing 60 via a pin. In the present embodiment, the first rod member 43 includes a first end portion 431, a second end portion 432, and a second pulley 433 that face each other. The first end portion 431 of the first rod member 43 is connected to the housing 60 via a pin, and the second pulley 433 is arranged at the second end portion 432 of the first rod member 43. When the distribution lever 10 is displaced along the direction of the feed input F1, the distribution lever 10 comes into contact with the second pulley 433 in the first rod member 43, and the first rod member 43 is the first end portion 431 of the first rod member 43. Rotates around. When the first rod member 43 rotates about its first end 431, the first rod member 43 pulls the second delivery assembly 50 of the drum brake mechanism to generate the second feed output F4. The second feed output F4 of the second delivery assembly 50 and the first feed output F2 of the first delivery assembly 30 are transmitted to the front wheel brake mechanism and the rear wheel brake mechanism with equivalent rigidity, respectively, and the front wheel braking force and the rear wheel brake are transmitted. The force ratio becomes a non-linear relationship as the input / input F1 changes.

FIG. 15 is a diagram showing an initial state of the brake interlocking system according to the second embodiment of the present invention. FIG. 16 is a diagram showing an operating state of the brake interlocking system according to the second embodiment of the present invention. In the present embodiment, when the brake interlocking system 1a is in the initial state, the distribution lever 10 is held in the initial position due to the limitation of the start delay assembly 40a. In the initial state, the distribution lever 10 further maintains the distance of the force distribution assembly 40b from the first rod member 43, that is, the second pulley 433 in the first rod member 43 does not abut on the distribution lever 10. At this time, the force distribution assembly 40b does not receive contact stress or pulls the second delivery assembly 50, so that the second feed output F4 is 0 (see the solid line portion in FIG. 2). In other words, in the displacement of the distribution lever 10 by the feed input F1, the numerical value of the second feed output F4 is 0 before the distribution lever 10 is brought into contact with the second pulley 433 in the first rod member 43. That is, the brake interlocking system 1a controls so that the front wheel braking force is generated slower than the rear wheel braking force, so that the first delivery assembly 30 of the rear wheel braking mechanism is braked first and the rear wheels are braked. Can be locked before the front wheels to reliably stop the rotation. In another embodiment, if the first delivery assembly 30 of the rear wheel brake mechanism does not generate the first feed output F2 due to stress (eg, disconnection, lockup, etc.), the distribution lever 10 is limited by the start delay assembly 40a. , It is not possible to further abut the first rod member 43 to drive the second delivery assembly 50 of the front wheel brake mechanism to generate the second feed output F4. That is, the brake interlocking system 1 of the present invention can not only match the front wheel braking force and the rear wheel braking force, but also function as a safety mechanism. If the first delivery assembly 30 of the rear wheel brake mechanism fails (for example, disconnection or lockup), the second delivery assembly 50 of the front wheel brake mechanism does not generate an interlocking braking force.

On the other hand, when the feed input F1 drives the distribution lever 10 to cause displacement and the distribution lever 10 starts to come into contact with the second pulley 433 of the first rod member 43, the first rod member 43 has its first end. Rotating around 431, the first rod member 43 pulls on the second delivery assembly 50 to produce a second feed output F4. When the distribution lever 10 drives the force distribution assembly 40b and pulls the second delivery assembly 50, in addition to changing the contact position between the second pulley 433 and the distribution lever 10, the rotating member 41 of the start delay assembly 40a Since the elastic member 42 resists the modulation force F3 and the modulation force F3 generated by the rotating member 41 of the start delay assembly 40a and the elastic member 42 changes more non-linearly, the second feed output F4 of the second delivery assembly 50 And the change in the ratio of the first feed output F2 of the first feed assembly 30 also have a non-linear relationship (shown by the solid line in FIG. 2). As the distribution lever 10 is displaced along the direction of the feed input F1, the modulation force F3 generated by the rotating member 41 and the elastic member 42 of the start delay assembly 40a gradually decreases. The gradually decreasing modulation force F3 increases the amount of increase in the second input F4 with respect to the gradually increasing input F1. That is, the second feed output F4 of the front wheel braking force is slower than the generation of the first feed output F2 of the rear wheel braking force, and the second feed output F4 changes non-linearly with the modulation force F3 as the feed input F1 increases thereafter. Decreases with. The change in the ratio between the second feed output F4 and the first feed output F2 has a non-linear relationship, and by reducing the difference between the second feed output F4 and the first feed output F2, the braking efficiency of the front and rear wheels can be effectively improved. Improve. As a result, in the brake interlocking system 1a of the present invention, when an emergency brake or a brake is applied on a wet road surface, the rear wheels are locked before the front wheels and stop rotating. If the rear wheel brake mechanism has a defect (for example, disconnection or failure), the front wheels do not generate interlocking braking force. Even if the front wheel brake mechanism fails, the rear wheel brake mechanism can generate sufficient braking force.

FIG. 18 is a diagram showing another installation example of the brake interlocking system according to the second embodiment of the present invention. As shown in the drawings, the brake interlocking system 1a of the present invention can be applied to, for example, a two-wheeled vehicle. The first delivery assembly 30 and the second delivery assembly 50 can be a rear wheel drum type brake mechanism and a front wheel drum type brake mechanism, respectively. The distribution lever 10 and the distribution force ratio adjusting mechanism 40 are provided, for example, inside the housing 60 (see FIG. 11), and their positions can be adjusted according to actual usage requirements. For example, the brake interlocking The system 1b may be provided between the left and right handles, or may be provided inside the vehicle body so as to be connected to the first delivery assembly 30, the second delivery assembly 50, the feed assembly 20, and the like. The present invention is not limited to these. As a result, the user can control the first delivery assembly 30 and the second delivery assembly 50 of the brake interlocking system 1b by controlling the feed assembly 20 with the left handle, for example, and the brake interlocking system 1 is non-linear. It is possible to provide the second feed output F4 and the first feed output F2 with a variable and accurate distribution ratio (the part shown by the solid line in FIG. 2), complete the braking interlocking of the front and rear wheels, and comfort the vehicle braking. The property, maximum deceleration and stability can be obtained.

FIG. 19 is a diagram showing an interlocking relationship of each configuration of the brake interlocking system according to the third embodiment of the present invention. In the present embodiment, the brake interlocking system 1b is the same as the brake interlocking system 1a shown in FIGS. 11 to 18, and the same components are designated by the same reference numerals and description thereof will be omitted. In the brake interlocking system 1a having a configuration different from that shown in FIGS. 11 to 18, in the present embodiment, the first delivery assembly 30 and the second delivery assembly 50 are, for example, a rear wheel drum type brake mechanism and a front wheel disc type brake mechanism. Can be done. In the present embodiment, the force distribution assembly 40b acts on the second delivery assembly 50 of the disc brake mechanism by a contact method. The second feed output F4 of the second delivery assembly 50 and the first feed output F2 of the first delivery assembly 30 are transmitted to the front wheel brake mechanism and the rear wheel brake mechanism with equivalent rigidity, respectively, and the front wheel braking force and the rear wheel brake are transmitted. The ratio with the force has a non-linear relationship with the change in the input / output F1. As can be seen by comparing the brake interlocking system 1a of FIG. 14 and the brake interlocking system 1b of FIG. 19, the force distribution assembly 40b can act on the second delivery assembly 50 by a pulling or contact method. The present invention is not limited to the sliding connection method of the distribution force ratio adjusting mechanism 40 and the second delivery assembly 50, but is omitted here.

FIG. 20 is a diagram showing an installation example of the brake interlocking system according to the third embodiment of the present invention. FIG. 21 is a diagram showing another installation example of the brake interlocking system according to the third embodiment of the present invention. As shown in the drawings, the brake interlocking system 1b of the present invention can be applied to, for example, a two-wheeled vehicle. The first delivery assembly 30 and the second delivery assembly 50 can be, for example, a rear wheel drum type brake mechanism and a front wheel disc type brake mechanism, respectively. The distribution lever 10 and the distribution force ratio adjusting mechanism 40 are provided, for example, inside the housing 60 (see FIG. 11), and their positions can be adjusted according to actual usage requirements. For example, the brake interlocking The system 1b may be provided between the left and right handles, or may be provided inside the vehicle body so as to be connected to the first delivery assembly 30, the second delivery assembly 50, the feed assembly 20, and the like.
